Jay Evans, manager of Riverwalk LLC, the development company behind the project, said 12 acres of the 22.5-acre site will be cleared for the low-density office park dubbed NorthBank.

“We’re not disturbing any wetlands,” Evans said. “It’s supposed to be a very natural, high-end office park.”

The site, portions of which are owned by the Randall, Birthright and Spigener families, is expected to be available to individual tenants by April. And because it is zoned as a planned unit development, any changes to the proposed site will go before the City Council for review and approval.

Evans said the lots will be sold and tailored to meet the needs of each business, which could include offices for doctors, lawyers or architects, among others.

However, no buyers have yet been lined up.

“We’ve not advertised or done anything as far as that goes,” Evans said. “I think it would be a great place for medical offices, because it’s in close proximity to both hospitals, but it’s not limited to physicians’ offices.”

In documents submitted to City Hall as part of the planned unit development approval process, developers estimate the clearing and site preparation construction to total about $3 million.

Utilities will be installed underground, and the conceptual plan shows lots ranging from 7,000 to 30,000 square feet. However, the plans are subject to change, Evans said.

“As we convey the lots, we’ll let the people come to us and make sure (the lot size) fits; then we’ll start drawing the lines from there,” Evans said. “None of (the conceptual plan) is etched in stone.”

The site is adjacent to a proposed 100-acre, multiuse development that was announced in 2007.

The NorthRiver Town Center, however, never came to pass after nearby residents in the Woodridge subdivision protested the development over concerns including increased traffic, light pollution and the possible effects such a large-scale development would have on the nearby environmental and ecological systems.

This development conforms to the current BN, or neighborhood business, zoning and did not get the public scrutiny that met NorthRiver Town Center.

Additionally, the NorthBank office park has not been the subject of any residential protests. Its designated use will not lead to similar traffic concerns, and Evans stressed that much of the land’s natural areas will be kept intact.

“It’s supposed to be for people who appreciate a real tranquil environment, conducive to being on the river,” he said. “Our idea isn’t to develop every square foot of the project. When you go to NorthBank, you’re in a first-class office park.”
